-- Question: How does my geographic location affect my seasonal allergy symptoms, and when should I consider moving to a different area as a result of my allergies?
Answer: The geographic location of the country clearly affects the pollen counts that one is exposed to and the type of pollen one is exposed to. In the warmer climates, for example in the south, the pollen seasons are much longer for all the various trees, grasses, and weeds. In addition, on the east coast for example, ragweed which is a heavy allergen tends to have a very robust season whereas in the mountain states, ragweed's not as much of a factor.
Another example is a year-round allergen such as dust mite. It only exists in humid climates and again in the mountain states where it's arid, we don't see as much dust mite. So geographically depending on where you live, the length of the season, and the type of pollen you're exposed to is determined by the local climate and that area.
